1 Safety Considerations
This system designates the use of laser products of the following class.
In case of FV5-LD405
CLASS III b(CDRH)
CLASS 3B IEC60825-1:1993+A1:1997+A2:2001
EN60825-1: 1994+A11:1996+A2:2001
JIS C6802: 997+A1:1998
In case of FV5-LD440
CLASS III b(CDRH)
CLASS 3B IEC60825-1:1993+A1:1997+A2:2001
EN60825-1: 1994+A11:1996+A2:2001
JIS C6802: 1997+A1:1998
Laser products of class 3B can only be used under control of laser safety officer. Before using laser products, refer to Chapter 4 – “USER’S SAFETY PROTECTION MEASURES ACCORDING TO IEC60825- 1:1993+A1:1997+A2:2001 “LASER PRODUCT RADIATION SAFETY STANDARD”, and exercise adequate countermeasures and then, use the laser products. Should you have any open question, contact our local sales office.
Caution when using
Pay your utmost attention to the following points.
When red LED’s of LASER EMISSION on FV5-LDPSU are lighting, it indicates that laser is being emitted. When microscope is connected, the laser is emitted from objective tip. Reflection may enter your eyes or light may be scattered around. Care must be taken in this case. In addition, do not see the sample while laser is scanning. 
When two red LED’s are lighting, it means “laser emission”.
I. SAFETY GUIDE

Safety Considerations
Regarding settings of DIP switches located at back panel of FV5-LDPSU, refer to VI 1 – 
Back panel switch settings.
zSet this system on robust base.
zThis system generates heat. When installing this system, make it sure that a space of 10cm or more is provided, left and right of the system, and do not block vent openings.
zPower cable may be molten when it hits hot place of lamp housing. When installing, make it sure that the power cable is adequately apart from the lamp housing.
zNever insert a metal piece into vent opening as it may cause failure or electric shock.
zDo not apply your hand or finger to laser beam that comes from mounting hole of objective lens or objective tip.
If your hand or finger is exposed to laser beam, it may cause a skin hazard. In addition, never insert a mirror into light path as the laser beam may come outside and it may enter your eye which is very dangerous
zDo not set or remove the sample during laser emission (laser scanning). If you set or remove the sample in such a case, reflection from the sample may enter your eye which is very dangerous. Moreover, do not look at the sample during laser emission (laser scanning).
zSystem performance as well as system safety cannot be guaranteed in case that cover is detached or the system is disassembled with use of tools. Never disassemble the system.
zDo not bend or pull fiber excessively. Do not step on the fiber. If the fiber is broken, laser beam may leak which is very dangerous. In case that such unlikely event occurred, turn power of laser power supply unit to OFF position immediately and contact our sales office. (when using FV5-LD405 only)
zAlways use the power cord provided by Olympus. If no power cord is provided, please select the proper power cord by referring to the section “PROPER SELECTION OF THE POWER SUPPLY CORD ”at the end of this instruction manual.
I. SAFETY GUIDE
I . 1 - 2 Page
Safety Considerations
zConnect the power cord correctly and ensure that the ground terminal of the power supply and that of the wall outlet are properly connected. If the equipment is not grounded, Olympus can no longer warrant the electrical safety and performance of the equipment.
zBefore connecting cord and cable, verify that the main switch is turned to O – (OFF) position.
zMixture (alcohol (3): ether (7)) that is used for cleaning optics is high inflammable so that utmost care must be taken when handling with respect to fire and main switch ON/OFF. When using ether, it is recommended that the room is well-ventilated.
zBe careful so as not to apply any excessive force to connecting cord or cable as it is very weak against bend or twist.
zDo not change fuses that are located above the power cord connector. When change of fuses is required, contact and consult with our local sales office.
zDo not carry the semiconductor laser head by hand. It may be damaged as it is very delicate tool.
zDo not swing around fiber carelessly. If fiber being emitted is swung around, laser beam may hit human body that would cause a hazard. (when using FV5-LD405 ONLY)
zWhen you dispose of this system, it is necessary to handle it as an industrial waste. In case that you cannot dispose it yourself, deliver it to our local sales office.

USER’S SAFETY PROTECTION MEASURES ACCORDING TO IEC60825-
1:1993+A1:1997+A2:2001 “LASER PRODUCT RADIATION SAFETY STANDARD”
10 Safety precautions
10.1General
This section specifies safety precautions and control measures to be taken by the user of a laser product, in accordance with its hazard classification. Often users can use the manufacturer's classification of the product for classification of the laser installation, thus avoiding all measurements. This section is supplied for the user's information. Nothing in this section shall be considered as constraints or requirements imposed upon the manufacturer. For installations where Class 3R laser products emitting energy outside of the 400nm to 700nm wavelength range or Class 3B or Class 4 laser products are operated, a laser safety officer should be appointed. It should be the laser safety officer’s responsibility to review the following precautions and designate the appropriate controls to be implemented. If should be the laser safety officer's responsibility to review the following precautions and designate the appropriate controls to be implemented. Wherever practicable, laser protective enclosures should be used for lasers of Class 3B or Class 4. Warning labels should be placed upon removable parts of protective enclosures or at service connections where a hazard is introduced by their removal or by disconnection.
The purpose of safety precautions and control measures is to reduce the possibility of exposure to hazardous levels of laser radiation, and to other associated hazards. Therefore, it may not be necessary to implement all of the control measures given. Whenever the application of any one or more control measures reduces the possible exposure to a level at or below the applicable MPE, then the application of additional control measures should not be necessary.
If a user modification of a previously classified laser product affects any aspect of the product's performance or intended functions within the scope of this standard, the person or organization performing any such modification is responsible for ensuring the reclassification and relabelling of the laser product.

USER’S SAFETY PROTECTION MEASURES ACCORDING TO IEC60825- 1:1993+A1:1997+A2:2001 “LASER PRODUCT RADIATION SAFETY STANDARD”
10.2Use of remote interlock connector
The remote interlock connector of Class 3B and Class 4 lasers should be connected to an emergency master disconnect interlock or to room, door or fixture interlocks (see 4.4).
The person in charge may be permitted momentary override of the remote interlock connector to allow access to other authorized persons if it is clearly evident that there is no optical radiation hazard at the time and point of entry.
10.3Key control
Class 3B and Class 4 laser products not in use should be protected against unauthorized use by removal of the key from the key control (see 4.5).
10.4Beam stop or attenuator
The inadvertent exposure of bystanders to laser radiation from Class 3B or Class 4 laser products should be prevented by the use of the beam attenuator or beam stop (see 4.7).
10.5Warning signs
The entrances to areas or protective enclosures containing Class 3B and Class 4 laser products should be posted with appropriate warning signs.

USER’S SAFETY PROTECTION MEASURES ACCORDING TO IEC60825-
1:1993+A1:1997+A2:2001 “LASER PRODUCT RADIATION SAFETY STANDARD”
10.6Beam paths
The beam emitted by each Class 1M and Class 2M laser product classified under condition 1 of table 10, each Class 3R laser product emitting energy outside of the 400nm to 700nm wavelength range, and each Class 3B or Class 4 laser product should be terminated at the end of its useful path by a diffusely reflecting material of appropriate reflectivity and thermal properties or by absorbers.
Open laser beam paths should be located above or below eye level where practicable.
The beam paths of Class 3R laser products emitting energy outside of the 400nm to 700nm wavelength range and Class 3B or 4 laser products should be as short as practicable, should have a minimum number of directional changes, should avoid crossing walkways and other access routes, and should, where practicable, be enclosed. The beam enclosure (for example, a tube) should be securely mounted but preferably not rigidly attached to (or provide support for) beam-forming components.

USER’S SAFETY PROTECTION MEASURES ACCORDING TO IEC60825- 1:1993+A1:1997+A2:2001 “LASER PRODUCT RADIATION SAFETY STANDARD”
10.7Specular reflections
Care should be exercised to prevent the unintentional specular reflection of radiation from Class 3R, Class 3B or Class 4 laser products. Mirrors, lenses and beam splitters should be rigidly mounted and should be subject to only controlled movements while the laser is emitting.
Care should be exercised to prevent the unintentional specular reflection of radiation from Class 1M and Class 2M laser products from surfaces that may focus the beam.
Reflecting surfaces that appear to be diffuse may actually reflect a considerable part of the radiation beam specularly, especially in the infra-red spectral range. This may be potentially hazardous for longer distances than one would expect for purely (Lambertian) diffuse reflections.
Special care needs to be taken in the selection of optical components for Class 3B and Class 4 lasers and in maintaining the cleanliness of their surfaces.
Potentially hazardous specular reflections occur at all surfaces of transmissive optical components such as lenses, prisms, windows and beam splitters.
Potentially hazardous radiation can also be transmitted through some reflective optical components such as mirrors (for example, infra-red radiation passing through a reflector of visible radiation).
